To the best of my recollection:
By season:
- Season 1: 7 times
- Season 2: 6 times
- Season 3: 5 times
- Season 4: 5 times
- Season 5: 4 times
- Season 6: 4 times
"All the way through":
- Original TV broadcast - 2004-2010
- DVD binge-through - 2014
- Blu-ray & DVD binge-through - 2022-2023
Breakdown:
- I watched each season on TV as it aired (with the exception of a few episodes from Seasons 1-3 that I missed during the original broadcast and didn't see until I owned them on DVD).
- I bought Season 1 on DVD in October or November 2005 and watched it again then.
- I bought Season 2 on DVD after Christmas 2006 and watched Season 1 and Season 2.
- I bought Season 3 on DVD in June 2008 and watched Season 1, Season 2, and Season 3.
- I bought Season 4 on DVD after Christmas 2008, and watched it by itself without the other seasons.
- I watched Seasons 1-4 in the fall of 2009. I got Season 5 on DVD for Christmas 2009 and watched it again by itself.
- I bought Season 6 on DVD in August 2010 and watched it again by itself.
- I watched Seasons 1-6 in Spring 2014.
- I watched Seasons 1-6 from September 22, 2022 - January 14, 2023.
There are some episodes I have watched by themselves instead of part of a binge, so those episodes have even higher numbers.
